I've felt like the powers that be have wanted, in some (but not all) seasons, to help our rivals
The brilliant things about Pep's City, is that he makes it as difficult as possible for refs to influence games against us (until now, perhaps). By dominating possession, we don't have to tackle as much, reducing chances for decisions and cards against us. We also do our best to keep teams out of our penalty area, again reducing chances of bad decisions impacting our results. All has meant that there have been games, where even if a ref has wanted to fix a game against us, they just wouldn't be able to without doing something ridiculous.
However, now refs have stumbled upon something they can do. Stop penalising late tackles on us when we keep possession. Stop booking players for first half fouls against us.
They don't have to make shocking decisions, they just have to ref both sides similarly, but reffing in this style works against us. And nobody even notices it.
And then when really bad decisions go against us, nobody really cares anyway apart from us. Because that's how tribal football fans are.
